Our goal is to conduct foreign exploration in Asia for parasitoids of spotted wing drosophila (SWD). Live material will be imported to US Quarantine where potential agents will be carefully evaluated for their effectiveness as SWD biological control agents, as well as for their potential risks to resident drosophilids. The long term goal is to identify the best natural enemies and then obtain USDA APHIS permits for field release and evaluation.
Collections in Asia will be guided by all available information on the location, host crops, host fly species and parasitoid species attacking SWD and related drosophilids. Collections will often be novel, as relatively little preliminary work has been completed. We will be aided by Asian collaborators. Field surveys of SWD parasitoids will be conducted in regions with known populations and then extended to other regions. In each location, targeted small fruit crops will be inspected for SWD-infested fruit, which, when found, will be taken to the laboratory for the rearing of parasitoids. Live species will be imported to the US quarantines. We anticipate several initial trips for surveys in China, Korea and Japan; followed by recollections will be made by cooperators, with one or two annual trips to search new areas. To test the effectiveness and host specificity of discovered Asian parasitoids on SWDs, experiments will be conducted in quarantine using laboratory colonies of SWD, selected resident drosophilids and parasitoids reared from fruit traps and collected fruit. Drosophilid colonies will be established on simple artificial diets.
